If you love fashion, you will know the importance of sunglasses. These are probably the most widely used, loved, and purchased fashion accessories. A pair of stylish, cool, and fashionable sunglasses enhances your style and persona when you go out. But they are not just for fashion. Sunglasses have several other benefits as well. For instance, it protects your eyes from the sun. But isn’t that already understood?
Anyways, just as technology is constantly evolving in everything, so is the case with sunglasses. If you own several pairs of sunglasses, you will know about polarized sunglasses.
Polarized sunglasses use a technology that has several benefits. It actually protects your eyes, helps clear vision, and reduces the strain on them. Despite the simple benefits, the technology or science behind it is pretty confusing. But who needs to understand the science when you are getting the features you have paid for?
Unfortunately, not every pair of sunglasses is polarized. Some might claim that they are, but they can just be tinted shades. Instead, shades look just like the polarized ones, but it is just a film coat on the lenses. So, you can validate the claim for yourself as well.

Here are a few signs that will tell if your sunglasses are not polarized. But before we move forward, let’s have a quick review of what polarized sunglasses are.
What are polarized sunglasses?
If you have been interested in physics lessons, you will know that it scatters in every direction when light hits a surface. However, when the light hits a polished surface, waves focus on a single direction. As a result of which, a sharp flash is created. But, with polarized glasses, these intense flashes are reduced to a greater extend. That’s because of the unique chemical that coats the glasses. This coat acts as a filter allowing only softer waves to pass through and stopping brilliant and harsh light waves. As a result, it improves your vision and reduces the stress on your eyes.
Signs that your sunglasses are not polarized
Now, if you are wondering whether your shades are polarized or not, there are several ways to find out. However, if you are having the following issues, then it is clear that the claims are not valid.
1. Your eyes get tired or hurt
The main aim of polarized shades is to comfort your eyes and to reduce the stress on them. When you are out in the sun, the bright rays make it impossible for you to see. Because of the so many reflective surfaces around you, combating with constant light waves and beams can be very tiring for your eyes. So, when you wear your polarized shades, the aim is to filter out the harsh rays so that your eyes are not stressed out. But if they are still weary every time you go out, even with your shades, there is a higher chance that you don’t own a pair of polarized sunglasses, and they are just tinted.
2. Your vision is somewhat blurred with the shades
Polarized shades don’t blur out your vision as they stop the harsh waves from passing through. You will still be able to see clearly but with less intense light. However, if wearing the shades make your vision blur, there is a possible change that they are not polarized. The technology doesn’t affect the quality of your vision at all. So, if it does, you are having fake shades.
3. You need to squint for a better view
What happens when you are out in the sun with your naked eyes? The sunlight or the reflections of the light get into your eyes, and you either have to put the hand on your eyes or squint to see clearly. That’s because of the sharp and harsh light waves. So, as you wear polarized shades, you don’t have to squint anymore because there is no intense ray entering your eyes. So, if you still have to squint while driving despite the polarized shades, it is a clear indication that they are not polarized at all!
4. LCD and laptop’s display aren’t dim
Here is a simple test that will tell you whether your shades are polarized or not. All you have to do is sit in front of the LCD or laptop display with your sunglasses. The display will naturally be dim than when you see it with your naked eyes. Now tilt your head sideways, and if your vision gets blacked out, it means the shades are one hundred percent polarized. However, if there is no change in the vision at all, it clearly indicates that you haven’t received what you have paid for.
5. The 60-degree test
Another valid and straightforward test you can perform with your sunglasses is the 60-degree test. Take the pair of sunglasses in your hand. Look at both sides, and they will have the same output. Now slowly start tilting the shades to one side at about a 60-degree angle. Just as you are moving it, you will notice that one lens, i.e., the one that is upwards, will have a glare, whereas the one that is downwards will blackout completely. You can clearly see the difference in both lenses. However, if there is no difference at all and the vision of both the lenses is identical, the sunglasses are not polarized!
The science behind this technology is quite impressive and comes with a price tag as well. However, you can encounter fake shades that claim to be authentic but end up as an utter disappointment. So, before you go out to buy a pair of polarized shades, make sure you keep in mind these points as mentioned above so that you can perform these tests at once. Furthermore, look out for these signs in your existing glasses, and if you don’t get the desired results, you need a new pair.
